with machines orapparatusfof the kind described,

wherein la series' of .fastener elements are attached, at spaced intervals, on a workpiece` in the movement of a workpiece supportingtable in two directions in the machine, that 'is to say, attachment of one series to a workpiece in movement of the table in one direction and another series` to another workpiece in movement of the table in the opposite direction, thereby avoiding lost motion in the machine of the kind under consideration. u

15 calms. (c1. 218-6) Considering Figs. 1 and'2 ofthe drawing, we have shown, at l5, a drive pulley driven by a belt IB from a suitable driving source for* rotation of a drive shaft of the machine. The shaft Il is supported in suitable bearings, as at I8, at the upper part of the casing or frame I9 of the machine.

The shaft '|'l 4is driven through a suitable clutch mechanism, generally identified at -20 in Fig. 9 of the drawing, through actuation of a primary pedal 2| shown in Fig. y1 of the drawing. The actuation of the clutch or other mechanisms of the machine or apparatus will be later described. The

casing or frame I9 is supported ona bed-plate `z'mounted'for quick detachable coupling with the shaft endthroughv the mediumfof a large clamp nut`29.' I'Ihisprovides re-placement of cam discs'- from time to time to suit different travel and spacing of'fasteners on supports or workpieces of different types and kinds, for eX- ample, in spacing fasteners on the separate parts ofapairf'ofshorts 30,' indicated in partinFig. In this figure, 3| represents a series vof.fstudparts'and 32 a series of-sccket parts for engagementwith the stud parts 3|, in what are commonly referred to as snap fasteners.

The workpiece, such for example asi 30, is

Yadaptedfor support upon a; workpiece supporting table or yplatform vmounted to move across the front of the machine'from right to left, and left to right, the-tablel having spaced brackets .311 and 35 secured to thelower portions thereof.

Each vbracket has a pairL ofv aperturesl in whichV are mounted a pair of'guide rods 3E, the latter slidably engagingv` spaced pairs of bearings 3l in a.

frame '38 pivoted to the main frame, as seen at 39, and adjustably clamped to the main frame I9 byv-aclamp-screw 1li] and a clamp hook 4|, note Figs. 1, Ll `and 10. The pivoted frame 33 has side walls with arc-shaped recesses 42 therein for movement over pin or screw portions, as at 43, on. one oiA which*v is arranged the clamp screw ll-and the other of which is arranged by the clamp hook 4|, the hook 4| being pivoted to the frame 33, as seen at 4|' land has. a fingerpiece portion at its free end, as at llll.

o The .rearV central portionsfof the table 33y is cutout, as seen at 33 and, adjacentthe cutout porand a secondary pedal ZI.'

tions, the surface of the table has roughened sections 33 to grip a workpiece, such as 39, urged upon said surfaces by fingers 49 and 59 each supporting yieldable pad members 49', 59. The fingers are -adjustably secured longitudinally of a square rod 5I to engage workpieces of different sizes.

The gauge attachment, which comprises most of the mechanisms of the machine described, constitutes part of a fastener setting or securing machine of any type or kind and, in Fig. 1 of the drawing, we have indicated at 52 the punch for setting the upper fastener part fed into position through suitable guides, as at 53, onto the workpiece or another fastener part 54 arranged on a suitable support. This determines a fastener locating station, which is also indicated by representation of the fastener 54 in Fig. 2 of the drawing and this station is exposed to the cutout portion 33 of the table 33. tion defined by the fastener 54 is an adjustable workpiece stop or gauge 55, against which the edge of the workpiece, for example the edge note Fig. l1, is adapted to be placed. The gauge is adjustably clamped on the table 33, as will appear from a consideration of Fig. 2 of the drawing.

Adjustably supported on the frame 38 are two other workpiece guides 5S, 56 arranged longitudinally with respect to the table and against which an edge of the workpiece is adapted to be placed, for example, the edge 39, note Fig. 1l, in gauging the spacing of the fasteners inwardly with respect to said edge. The shaft 5I is rotatably supported in brackets 51 secured to the brackets 34-35. Secured to the shaft 5| beyond one of the brackets, the bracket 51 to the right of Fig. l, is an arm 58, which extends downwardly and has a surface 58 normally held against an elongated plate 59 by a spring 60, note Fig. 3.

The spring 60, when the plate 59 releases the arm 58, also is of sufficient tension to support the fingers 49, 59, or their pads 49', 59', in firm engagement upon the work. The plate 59 is supported, at its ends, by arms 6I, 6I mounted on an elongated rod or shaft 62 supported in end bearings of a bracket plate B3, note Fig. 2. The arm 5I differs from the arm 6I in having an integral extension Si" Athereon forming a bellcrank of said arm, as will clearly Vappear from a consideration of Fig. 3. The arms are adapted to move the plate 59 to free the fingers 49, 59 for gripping action, as later described. apparent that the frame 38 and the several parts coupled therewith constitutes a swinging frame unit, which is adapted to swing forwardly and downwardly into the dotted line position, as seen in Fig. 8 in order to give free access to the fastener mechanism of the machine and, particularly, the Ifeed and guide for the fastener 54. Swinging movement of the frame unit is accomplished by simply releasing the screw or nut and the clamp hook 4I. Upward movement of the frame unit is checked and controlled by an adjustment screw 54 adjustably supported in the frame 38, note Fig. 8, and operating upon the part 34 on the frame I9, as clearly illustrated in said figure. The elongated plate 59 compensates for movement of the table into its different positions to aline the workpiece with respect to the station 54 in spacing the fasteners 3 I-32 at predetermined spacings longitudinally of the workpiece or apparel 30.

The machine, according to the present disclosure or illustration of one adaptation and use Adjacent the sta- 'f It will be of the invention, is to apply a series of three fasteners 3l or 32 in a successive series of automatic operations of the machine and in continued uninterrupted operations controlled by a single depression of the pedal 2 I. Let us say, -for example, that, in the first operation, fasteners are attached to the workpiece from left to right. Then, upon completion of the first cycle of three operations, another workpiece is inserted into the machine and another series of fasteners are attached in another cycle of operation, the fasteners being attached to the workpiece from right to left and in the reverse movement of the workpiece table 33. To control this operation, I provide a Geneva 65 having two sets of circumferentially spaced notches or recesses 55, 66', three notches being employed in each set and the Geneva carries, between the sets, opposed pins 61, 61'. The Geneva 65 is rotatably supported upon a lever 68, pivoted in the frame, as seen at 58'. This Geneva controls the two three cycle operations of the workpiece supporting table, as will later appear. It will be understood that the pulley I5 is freely rotatable on the shaft II and is clutched to drive the shaft II through the clutch mechanism 20, as later described.

Partially arranged in the hub of theY pulley I5 and keyed to the shaft I'I is a clutch driven member 69, and to member 59 in turn is keyed a disc ring lll. The disc ring T0, as shown in dotted lines in Fig. 9 and in section in Fig. 2, is provided with a projecting post 10', which is connected to a similar post II projecting from a clutch cage or stop disc I2 by a tension spring 'II which tends to urge saidstop disc I2 in a counterclockwise direction relative to the disc ring 'IIJ and the driven member 59. The stop disc 'I2 is mounted to freely rotate on a hub portion of the driven member 69 (note Fig. 2) between the ring disc I9 and a flange projection on said member 99. Projecting from and rigidly secured to the disc 'I2 are a series of circumferentially spaced clutch control elements 'I3 (note Fig. 9) operating between the clutch driven member 69 and that part of the pulley I5 overlying and spaced from said clutch driven member, for example, the flange portion I5 illustrated in Fig. 2 of the drawing, and shown in section in Fig. 9. The driven member 69 has a series of circumferentially spaced teeth or projections 69, between which and the elements 13 are freely disposed clutch rollers 14. The curvatures on eachl of the teeth or projections 69' form wedge-like surfaces so that, when the elements 13 are moved in the direction of the arrow X, Fig. 9, the rollers are free to move into the gripping or clutching position to transmit the constant drive of the pulley I5 to the shaft I'I through the driven member B9 attached to shaft I 1.

Arranged inwardly of the pulley I5, or to the left thereof, as seen in Fig. 2, is a brake-drum 'I5 keyed to the shaft I'I and this drum has secured thereto a projecting pin 15, which extends into the path of the geneva 55 to intermittently rotate said geneva a partial revolution in each revolution of the shaft I 1, as will clearly appear from a consideration of Fig. 3 of the drawing.

Arranged around the break-drum l5 are breakshoes 1B, 'I6' pivoted at 'II to the frame I9, Fig. 3. and having spring means, as at 'II', to apply a constant frictional engagement upon the drum controlled by the bolt TI so as to control rotation o-f the shaft I'I and the mechanism driven thereby and prevent excessive strains in stopping rotation of the shaft.

Y Connected withthe foot pedal 2| is a connecting rod 18 which couples, at its upperendywith a lever 19 pivoted, as seen at 19., yArranged above the lever 19 is a clutch arm 89 pivoted, as seen at 8|. Adjacent the pivoted endyof the arm is anY adjustable screw 32 cooperating with av stop 82 to set upward swinging movement of the arm,

upward movement 'being contributed Ato thearm by a spring' suitably fixed to a partof the machine or casing, not shown.

The free end of the arm 80 is adapted to be engaged by an offset or catch 84 ona link 85 pivoted to the lever 19, as at 85. A spring 8S is coupled with thepivot end of the lever 19 and to the link 85 to normally holdthe catch in engagement with the arm 8|! as will clearly appear from Fig. 3. The upper end of link 85 is forked and pivoted, as seen at 85" to a link-81, the latter beingl pivoted, as at 81', tothe forked,

Vportion of a Geneva engaging lever88, which isl pivoted to the lever' 68, as seen at 98. The lever L 88 has a projection. as at 93, adapted to be erigaged` by the pins 61, 61 of the Genevaso that,

upon completion of three cycles of operation of' the shaft I? and three intermittent partial rotations of the Geneva 6 5, one of the pins 61, 61 Ywill actuate lever 89 to disengage the catch 8410i lever 85 torrelease the clutch arm 89 when the latter is held in the downward position.

In Fig. 3 of the drawing, thearm 80 and the other associated parts are shown in what might be termed the normal stop-position of themachine. ,Upon depressing the foot `pedal 2|, the link 85, engaging the arm 80, will pull'the varm downwardly againstthe action of the spring 83 and, in thisv operation, the stop plunger 89 mounted in the arm 8|) is moved out of engagement with the projecting stop lug 12'. The

plunger 39 is advanced forwardly or outwardly by The :spring 89' a spring 89 to a stoppin 89". forms a means to cushion the blow when the lug 12 strikes the plunger89'in stopping a 'revolution of the shaft |1, as will be apparent the shaft y|92=to Vthe'right of the bearing |03 The free end of the lever isms .alink-cdnv Yneotion, as at 99, with-the'bell crank arm 6|, so

that, whenk the lever 19-is.drawn downwardly by the foot pedal 2| and connecting ro-d 18, simultaneously the plate 59 will be moved out of engagement with the lever 58 and the spring v5|) will then move both lingers v49 and 59 intorlrm enf gagement with the-workpiece which, at this time, `willlce positioned on the table 33 of the machine.

Upon releasing the stop lug or element12'in theaforesaid downward movement ofthe clutch arm, the spring 1| will cause the control elements 13 to move inthe direction of'arrow X, allowing f nally of -the shaft '|1-.

grooves, are of a contourto ,control the particular shifting of u the table as required-and the number of shiftings that may -be required. In the present illustration, three shifting ,stations areemployed to attach three fasteners, as at 3| -32,`to a garment at equally spaced distances and between the two shifting lstations are what' mightbe termed idling stations inthe cam groove as, vfor ,example, at 95, 96', the station'9liv controlling the v at 99', note' Fig. 1,:the forkedend 98 having rollers,98 operating in the sleeve 98 as in other `devices-of this kind'. f Coupled with the otherend 'of thebell crank-:99, is a rod lfwhich couples with anarm ||l|xsecured to one: end ofja long shaft |92 supported. in spaced bearings |03, |03' on Vthebase |94 of the machine, part of which is indicated in Fig. lof the drawing. The foot ypedalZ is secured to the shaft I 92 adjacent and to the left of the bearing |03 and coupled to an arm |95 ofthezpedal is an upwardly-.extending rodi |95. AThe pedal 2| is rotatably mounted on and has an arm |95', with Which-the rod vr18 is coupled. Secured tothe under-surface -of the pedalV 2| is a plate |91 which extends to theunder-surface of the. pedal 2|', so that, when `the pedalZI is depressedthe pedal 2| will beoorrespondingly depressed. On the other hand, the

pedal 2| can 'be depressed Ywithout Vactuation of pedal 2|. -The plate .|91 has a stop |08 for keeping the operators fooiry away from accidentally stepping onthe pedalf 2|'. Securedvtor therod 1B'and to `thebed plate `22 of the machinel is -a spring 18" which normally supports the pedal 2| Vinraisecl position. y*The pedal 2 is held in raised position byreason of spring |34 attachedtolever' l Itwill be understood, from the foregoing, that `the clutchpin or -bar 91is thrown out of engage- --ment 'with thegshaft l1 only when the pedal` 2 isdepressed and-in the Asingle Voperation of Athe machine, .or when the machine Visy used to se- V`curea single fastener. Q

the clutch rollers 14 tomove into clutching position; for the pulley 5 to operate the drivenV member 59, thus contributing rotationto the shaft l1 as will appear from a consideration of Fig. 9 of the drawing. Rotation of the shaft |1 causes theY worm gear 26 and worm 21 to be driven, thus actuating the shaft to rotate the cam 28. In the surfaceof the cam or cam disc '28 is a double cam groove 9|, one series of surfaces 9| of whichare adapted to control movement of the tablel 33 inone -direction and the other series9l" of which,

will actuate the table in the opposite direction,

'the table being operated by a long offset lever 92 pivoted, as seen at 93, and carrying at its upper end a roller 94 which operatesin the cam groove 9|. The other lower end of the lever has arolle'r 95 arranged 'in a yoke or recess portionofthe support 34 at the end of the table, the roller'SS operating upon bearing plates 95', as seen in Fig.

2 of the drawing. Each series 9|, 9|', in the cam I,('Jonsideringnow Fig. f3, of the drawing, it will "appearthat the upperend of the rod l 06 couples vwith one end of abell crank lgpivoted, as seen at H9, and the other. end 2| l of the bell crank vis-jpivoted to a link I2 coupled with vand movable longitudinally of an elongated slotv ||3pln the armii by coupling,v asat I4. Thev link |2 has a cam portion |25, note Fig. 6, which operatively engages the lower end portionV IB of a fingerV H1; note also in thisconnection Fig. 7 of vthe drawing. The finger H1 hasa two-way pivfotal or swinging mounting` upor'a raised portion This mounting comprises aA H8 ofthe arm 89.

` pin vv| i9 'rotatable inthe raisedportionll and entering vandoperating freely in an aperture |20 I .in thefinger andthe finger i1 has pivot portions |2| onthepinv H9.v It will, thus, be apparent-that Y.the finger |1 can'swing inwardly and outwardly with respect to the path of movement of the pin 15', as seen in Fig?, injwhich operation the finger swings onthe pivot axes |2| anc' can also swing at right angles to the rst movement'by rotation of the pin I I9 when the finger is engaged and operated by the pin 15. The lower end I I5 of the finger I I1 is forked, as seen at |22, to engage a'pin |23 ora bearing sleeve |24 thereon, the pin `|23 being secured to an elongated trip plate |25 mounted to move longitudinally of the arm 80 and to move the lever 85 to the left, as noted in Fig. 3, to disengage the catch 84 from the arm 80.

'|09 is a link |23 pivoted to the lower end ofthe lever or arm 68, as seen at |21, note Fig. 3. From the foregoing, it will appear that, as and when the pedal 2| is depressed, the bell crank |99 is actuated to move the upper end III thereof to the left, as seen in Fig. 3, thus withdrawing the wedge or cam surface I5 from the finger I I1, allowing the nger to be moved by a spring |28, ynote Fig. 3, into the dotted line position'of Fig. 7,

' that is, into the path of the pin 15. At the same time, the actuation of the bell crank |09 will move the arm or lever 68 to the left throwing the geneva 95 out of the path of the pin 15', thereby permitting single operation or rotation of the machine in applying a single fastener. In depressing the pedal 2|', the pedal 2| is also'deypressed which causes the arm 89 to be drawn downwardly and all of the other functions of the Vmachine, for example moving the fingers 49, 5D

y the machine.

In the aforesaid one-cycle of operation ofthe machine andthe pin striking the finger II'I,

the connector or trip plate Iis operated to disengage the catch 84 from the arm 89, allowing Athis arm to move upwardly by theV spring B3 to bring the stop plunger 89 in position to engage the projection 12' checking the machine after one revolution. It will be understood that, as the arm 89 is moved down in the initial operation, above "described, the stop plunger 89 moves out of the path of the projection 12, allowing the L shaft I1 to perform its single rotation. Upon releasing pressure of the foot upon the pedal 2|', the pedal will be returned to normal position, thus returning the parts to the normal position, as shown in Fig. 3, where the machine is at rest.

Either pedal 2|, 2|' may now be operated. If

the pedal 2 I is again operated for application of another single fastener, this can be done. n On the other hand, the pedal 2| my be operated to perform the three successive operations and these operations will beperformed as follows.

In actuating the machine to perform three suc- Vcessive operations or to apply three fasteners,

as at 3I--32, to a garment or other support, the following procedure will be followed. Here it might be well to mention rst, however, that one machine is used to apply one set of fasteners,

Vas at 3|, and another machine, the other set of fasteners, as at 32. After alining a workpiece, such as 39, upon the table 33 with the edge 39 up-against the stop or gauge and the edge 39" up-against the stops or gauges 53, 56', the pedal 2| is depressed and held depressed until after attachment of the third fastener. This draws downwardly upon the lever 19, which, through Also-A l pivoted to the upper end III of the bell crank 3 the link 99, bell crank 6 I releases the fingers 49, 50' to grip the workpiece in position upon the table 33. In the aforesaid downward movement of the lever 19,'the link 85 draws the arm 80 downwardly disengaging the stop plunger 89 from the projection 12. The spring 1| then puts the clutch into operation in the manner previously described causing the shaft I1 to be rotated. In the first complete revolution of the shaft, the pin 15 will rotate the Geneva 65 1/6 of a revolution to advance one of the pins, the pin B1, in the direction of the cam 88". In the beginning of the aforesaid operation, the fastener attaching means of the machine is actuated to apply a fastener to the workpiece, for example, the first fastener 3| to the left of Fig. 1l. In the above operation, the cam 2bV is rotated 1/6 of a revolution and, during this one complete rotary motion of the shaft I1. the arm 92 will be actuated by the cam to advance the table 33 (to the left in 2)V to position another portion of the workpiece in position for receiving, for example, the middle fastener 3| shown in Fig. ll.

Then the cam 28, by reason of the shape of cam groove 9|, will maintain a dwell in actuation of the arm 92 to hold the table 33 momentarily at rest and vsin'iultaneously the fastener attaching means of the machine will be again operated and at this stage the shaft I1 will be completing its second rotation, again actuating the Geneva 55 to advance the same another M; of a revolution and this operation is again repeated in attaching the fastener 3|, shown to the' right of Fig. 1l in the third rotation of the shaft I1, at which time theY pin 61 has engaged the cam surface 88" on the lever B8, moving said lever to the left, note Fig. 3, disengaging the catch 84 from the arm 89, allowing said arm to be drawn up- 'wardly by the spring 33 to bring the plunger 89 into the stop position, thus checking rotation of the disc 12 and disengaging the clutch driven member 69 attached to the shaft I1 from the drive pulley I5.

In each of the aforesaid attachments of the series of three fasteners 3|, the workpiece is retained in engagement with the table by the ngers 49, 59. However, upon removal of the foot from the pedal 2| the lever 19 will be raised (Fig. 3) which will automatically raise the fingers 49 and 59, allowing the workpiece to be removed from the table.

Another garment will then be positioned upon the table '33 when the latter is in its farthermost left position as viewed in Fig. 2 ,and the machine again operated to set the plural number of fasteners 3| or 32 to thegarment during thereturn movement of the table to the right.

the Vthree series of Yfasteners or the individual fasteners in. order to `maintain the fingers 49, 5I) in engagement with the workpiece.

Considering Figs. 2 and 8 of the drawing, it will appear that the workpiece guides 56, 53 are adjustably mounted to control positioning of the fasteners 3|, 32` with respect to an edge of the garment, forexample, the edge. 39". This adjustment consists-1in providing elongated slots |30, in the plate |3| of the frame 3i; and a clamp nut |32, |32 for holding the gauges 5E, 56' in position. Keys, one of which is shown at |33 in Fig. 8, are employed on the gauges to prevent rotatable shiftingthereof and to maintain alinement as will `be apparent.

Considering Fig. 3 of the drawing, a long spring |34- is shown extending between a pin |35 Von the bell crank lil-(to a suitable fastening on the frame of the machine,- as seenat |35. This spring urges the linkoi` lever ||2 to the'right,l as seen in Fig.'3, with the pin H4 in the left end of the elongated slot |13 and maintainsthe wedge ||5 in engagement with the finger i'. Note in this connection Fig. 6 of the drawing. The spring |34 alsosupports the pedal 2| in raisedposirtion when the pedal 2| is depressed. The spring |34 further operates through intermediate link- -age to hold the clutch pin 91 in operative position within the adjacent slotted end of shaft Il.
